THOMAS G SCONZO ATTORNEY WWWWW,

United States Patent 3,296,740 TENSIONED LOCKING DEVICE FOR LOUVRES ANDTHE LIKE Thomas G. Sconzo, Macon St., Sayville, Long Island, N.Y. 11782Filed July 3, 1964, Ser. No. 389,140 2 Claims. (CI. 4987) This inventionrelates to a tensioned locking device for window frame construction andmore particularly to an adjustable locking device for jalousies and thelike types of window and door construction wherein a portion thereof canbe opened and fixedly maintained in locked position.

The invention herein is an improvement of my invention described andclaimed in US. Patent No. 2,905,984, dated September 29, 1959.

In the types of jalousies heretofore used, it is to be noted that thereis provided an operating leverage mechanism for opening and shutting thelouvres constituting the jalousie. Such controlled operating mechanismis usually and preferably disposed at one side only of the jalousieframe and at the lower portion thereof for facility of use. It has beennoted, however, that said operating mechanism does not close the windowpanes or louvres tightly on the side opposite the mechanism. In fact,there usually is, at the end of the louvres or panes away from theoperating mechanism, a space between such louvres or panels when closedthus permitting air, wind and rain to come through such space because ofthe uneven locking of the louvres. Various types of control units havebeen used wherein there are double handles or screw mechanisms whichhowever, have not been very effective.

With the above disadvantages in view, it is an object of my invention toprovide a fool-proof uniform pressure locking mechanism in a window ordoor frame construction to effect a uniformly tight closing of thelouvres or panes at the portion away from the operating mechanism.

Another object of the present invention is to provide a controlledcamlock device for installation on the side of a jalousie frame to actas an auxiliary to the regularly used types of operating closingmechanisms so as to effectively close the louvres or panes of thejalousie and form a uniform seal at the contacting portions of thelouvres or panes.

Still another object of the present invention is to provide a tensioned,adjustable, regulatable auxiliary locking camlock device having a seriesof engaging sections in the device adapted to uniformly close or lockthe louvres or panes in unison thus forming a seal between the adjoininglouvres or panes when in closed position.

A more specific object of my invention is to provide a manuallyoperable, easily installable, adjustable locking mechanism for easyconnecting with an operating bar of a jalousie frame for effectivelyclosing the ends of the jalousie panes and form a tight seal thereat.

Other objects and features of the invention will become apparent fromthe following detailed description taken in conjunction with theaccompanying drawings, wherein:

FIG. 1 is a sectional broken away side view of a jalousie frameconstruction embodying a preferred form of my invention;

FIG. 2 is a sectional enlarged view taken on line 22 of FIG. 1;

FIG. 3 is a sectional view taken on line 3-3 of FIG. 2;

FIG. 4 is an exploded view of the components embodying FIG. 2; and

FIG. 5 is an enlarged view of a part of the embodiment shown in FIG. 4.

Referring now specifically to the drawings wherein like numbers refer tolike parts throughout, it will be noted that such jalousie may be for awindow or door type of construction. In said frame piece 13, there areprovided jambs 14 one on each side of the piece for accommodatingindividual louvres or jalousie panes 15 mounted in suitable retainingmembers 16 at each end thereof, which retaining members are pivoted tothe jamb 14 by means of pin members 17. Extending at an angle from saidretaining members are linkage arms 18 which in turn are pivota-llyconnected at 19 to an operating arm 20 which in turn extendssubstantially parallel to the major length of the jamb 14. Said arm 20because of its leverage controls the movement of panes 15 via linkagearms 18.

Said ope-rating arm 20 it will be noted from FIG. 1 of the drawing is inturn pivotally connected preferably at its lower portion, to a pivotedrod 21 which extends diagonally downwardly and is connected to amanually operable arcuately shaped adjustable locking member 22. Saidrod 21 is pivoted to said lock member by means of a pin 23.

Member 22, it will be noted comprises two portions, one a straight link24 which is connected at one end by means of pin 23 to member 21 whileat its other end it is provided with a cross pivot or pin 25. The otherportion 26 is curved and provided with a plurality of notches orindentations 27.

A housing 28 consisting of two engageable sections 29 and 30 form ahollow for accommodating said locking member 22. Also, the housing isadapted to accommodate the member 22 and link 24, which is movabletherein. Portion 29 has extensions 31 and 32 for attachment to jamb 14as shown in FIG. 1 by means of bolt or screw members 33.

Section 29, furthermore is provided on its side with a vertical slot 34and a threaded opening 35, while section 30 is a plate engageable withsection 29 and has extensions 36 and 37 which fit into grooves 38 and 39respectively. Section 30 also has an internally disposed side extension40 with a threaded opening 41 which is in alignment with opening 35 foraccommodating screw 42 so as to hold said sections 29 and 30 together injoined condition as shown in FIGS. 1 and 2. Furthermore, section 30 hasa slot 43 which with slot 34 accommodates pin 25 which is slidabletherein.

It will be noted that section 30 provides a housing for a block 44 and aspring 45. Said block as shown in FIG. 5 is of such shape as to fit in arecess 46 and held in position when said sections are joined. Spring 45fits inside an opening 47 in block 44 and rests at one end against afloor 48 so as to keep said block 44 under tension. Said block 44furthermore, has a protruding riding portion 49 on which the innerportion of arm 22 rides as shown in FIG. 3. Said spring exertssufiicient pressure to maintain arm 22 in any fixed position against thetop 50 and extension 31 to form a tight look when arm 22 is moved.

Also, pressure can be applied against said arm so that pin 25 can bemoved vertically in slot 34-43 against the pressure of spring 45 in thehousing. Said arm can be moved in a limited are about pin 25 as a pivotso as to actuate rod 21 to open or close the panes 15. The arm 22 can bemoved about pivot 25 so as to engage edge 48 with any of the notches.The tension on spring 45 is of sufficient force to hold the arm 26 inany set position.

In operating the device, the handle or curved member 26 is moved aroundpin 25 so that the pressure applied on said member 26 causes the innercurved part of the arm to ride on portion 49 of block 44 and against thepressure of, spring 45.

Notches 27 provide stops and also prevent further movement of the arm 26unless pressure is applied thereon to overcome the pressure of spring 45against block 44.

Furthermore, it will be noted that a wedge 42a is provided which fits inthe cavity 425. Said wedge can be adjusted by screw 42 and moved towardor away from the rounded portion of link 24 whereby said link is raisedor lowered on its pivot pin 25. By such use of wedge 42a, the pressureof portion 26 against recess 46 can be regulated. In order to facilitatethe sliding movement of link 24 on pin 25 against wedge 42a there isprovided a groove 420 in said Wedge.

While a preferred embodiment of the invention has been illustrated anddescribed herein it is to be understood that various modifications as toform, arrangement of parts and use of materials may be made withoutdeparting from the spirit and scope of the invention as claimed herein.

I claim:

An auxiliary locking device for operating a movable member forlouvres for tightly closing louvre panes and the like in a jalousieconstruction, comprising a housing attachable to one of the jambs of thejalousie construction, said housing having an opening therein, a notchedmovable elevating and depressing arm extending through said opening ofthe housing pivotally connected at one end to the movable member for thelouvres, said arm further having an extending portion pivotallyconnected in the housing, said extending portion being connectedintermediate the ends of said movable arm, means at the extendingportion for pivotally retaining said arm, riding tensioned means in thehousing for the pivoted arm in the housing, said notched arm engagingthe housing to permit setting of said arm, said housing being providedwith a movable wedge to regulate the movement of the extending portion.

2. A device according to claim 1 wherein the housing has a set screw andthe wedge is movable by said set screw in the housing, and the wedge hasa grooved channel to accommodate the end of extending portion.
